BACKGROUND OF THE INVENTION

In a variety of transactions, customers or buyers of goods or servicestypically receive receipts from their respective merchants or serviceproviders as proof of existence of conducted transactions. Generally,receipts are issued by merchants and service providers for a number ofreasons including, for example, regulatory or tax reasons andconvenience purposes. A receipt provides information about acorresponding transaction for the purpose of providing all participantswith a trace or record of the transaction. Receipts may be used forvarious purposes including, for example, proving participation in atransaction for tax reporting purpose; managing exception situationsarising from a transaction, such as, product return; facilitating asubsequent transaction between a service user and a service provider,such as, being used as a claim ticket for equipment on repair; orfacilitating provision of complementary services, such as, warranties.

Generally, receipts are provided in printed form. There is, however, anumber of shortcomings associated with printed receipts. For example,printed receipts contribute to operating costs for the merchants andservice providers. Also, printed receipts once they are issued to theconsumers are difficult to track and/or audit. This limited ability totrack and audit printed receipts makes them particularly susceptible tofraudulent uses (such as, forgery, misuse, etc.). Furthermore, from aconsumer standpoint, printed receipts have limited convenience inherentto their physical attributes.

In some systems, electronic receipts are stored on a portable device.However, storing of the electronic receipts is often performed on an adhoc basis and such systems do not provide any meaningful management ofthe electronic receipts after they have been stored.

Hence, it would be desirable to provide methods and systems that arecapable of addressing the foregoing and other issues and managing andusing electronic receipts in a more efficient manner.

The remote communication module of the base device 14 is capable ofcommunicating on a substantially real time basis with the electronicreceipts administration system 24. The remote communication module ofthe base device 14 may also interface with other systems involved inprocessing a transaction, such as, the service provider environment 22,which the base device 14 may query for transaction data.

The user device 16 is a device with computing and local storagecapability capable of communicating with the portable device 12 andother devices to perform a number of functions including, for example,retrieving electronic receipts from the portable device 12, storing theretrieved electronic receipts locally, displaying the electronicreceipts for management, and exporting information from the electronicreceipts for use with other applications and/or services that resideeither within or without the user device 16. Examples of a user device16 include personal computers, personal digital assistants (PDAs), cellphones and kiosks.

The user device 16 is a convenience system allowing the user tointerface with the portable device 12 for the purpose of managing theelectronic receipts stored in the portable device 12. The user device 16allows the user of the portable device 12 to manage the electronicreceipts stored on the portable device in a number of ways. For example,the status of the portable device 12 may be displayed by the user device16, such as, electronic receipt stored, memory available, etc. Theelectronic receipts can be displayed in an organized fashion by the userdevice 16. The user may exchange information between the portable device12 and the user device 16. The user may selectively delete electronicreceipts stored on the portable device 12 or transfer some or all of theelectronic receipts from the portable device 12 to the user device 16.The user may also selectively delete electronic receipts that werepreviously transferred to the user device 16 or download previouslytransferred electronic receipts from the user device 16 to the portabledevice 12. Electronic receipts on the portable device 12 may also beduplicated onto the user device 16, for the purpose of saving a copy ofan electronic receipt, which copy may include specific informationidentifying it as a duplicate.

In one embodiment, the user device 16 includes a communication modulecapable of interfacing with the portable device 12 through such means asdirect electrical connections, infrared communication or radio frequencybased communication; a display interface, such as, a screen, a printer,a keypad, touch screen, tablet, mouse and a system capable of providingan interface via the sense of sight or touch; a computing system capableof running specific control logic used to retrieve and displayelectronic receipts; a local storage component capable of storingelectronic receipts uploaded from the portable device 12.

The user device 16 may be configured for use directly in conjunctionwith the portable device 12 or other devices in an off-line manner toprovide local receipt management or to interface, through an opennetwork 28, with the electronic receipt management server 18, where theelectronic receipt storage and management functions are performed. Theopen network 28 may include the Internet, a local area network, a widearea network and other types of computer networks. Alternatively, theuser device 16 may communicate with the electronic receipt managementserver 18 via a dedicated communication link, such as, a dialup link, aT1 line and a T3 line, etc. The electronic receipt management server 18or other devices may or may not be owned and operated by the entityoperating the electronic receipts administration system 24. However,communications from the user device 12 and the electronic receiptmanagement server 18 and other devices may be secured or otherwise bedefined according to the specification provided by the administrationservice provider environment 20.

The electronic receipts administration system 24 is capable ofcommunicating with the base device 14 on a substantially real timebasis, directly or through an intermediary network, for the purpose ofmanaging the base device 14.

The electronic receipts administration system 24 includes control logicused to register and manage the base device 14. The base device 14 isassigned an unique base device identifier (UBDID) generated by theelectronic receipt administration system 24. In one implementation, theUBDID includes an unique number that can be used to identify the basedevice 14. Optionally, the UBDID includes a location identifier that isused to identify the location of the base device 14. The locationidentifier may contain sub-fields to not only identify a location butpossibly a lane or point of service location within the location. Thelocation may be a physical location or an Internet location.Furthermore, the UBDID may also include discretionary data, such as, aname, an address, and a phone number.

The electronic receipts administration system 24 may also use the UBDIDto identify the service provider involved in the transaction. The UBDIDmay further include information relating to a service provider. As aresult, base devices 14 belonging to a particular service provider canbe identified.

The UBDID may be constructed as a fixed identifier with specificsub-fields used for the unique number, location identifier, anddiscretionary data; or a variable length identifier made up ofdescriptor and data fields, the descriptor fields identifying the natureand length of the data, the data including the unique number, locationidentifier and discretionary data.

Information from the UBDID is incorporated into an electronic receiptgenerated by the base device 14. This allows the base device 14 identifyelectronic receipts that it generated. Furthermore, this provides addedsecurity with respect to access to the electronic receipts stored on theportable device 12 by the base device 14. The UBDID can be used as anauthentication check to ensure that the base device 14 only accesses theelectronic receipts that it generated.

The electronic receipts administration system 24 also controlsgeneration and management of electronic receipts by the base device 14by providing the data and control logic required locally by the basedevice 14 for the generation and management of electronic receipts. Forexample, the electronic receipts administration system 24 downloads theappropriate electronic receipt generation and management policy to thebase device 14 to allow the base device 14 to generate and manageelectronic receipts accordingly. Such policy include, for example,validity periods, conditions for retrieval, receipt securityrequirements, base device and portable device maximum storage capacity,or procedures for handling exceptions.

The electronic receipts administration system 24 further collects fromthe base device 14 information relating to the base device 14 and theelectronic receipts generated by the base device 14. Such data mayinclude data used by security algorithms to identify participatingportable devices 12 at the base device 14, generate secure electronicreceipts, and provide verification of integrity of an electronicreceipt.

The electronic receipts administration system 24 performs a number ofother functions. For example, the electronic receipts administrationsystem 24 may collect from the base device 14 electronic receipts storedon the base device 14 for storage on the electronic receiptsadministration system 24 for the purpose of freeing memory on the basedevice 14. Electronic receipts stored on the base device 14 areduplicated and stored on the electronic receipts administration system24 for the purpose of saving a copy of an electronic receipt, which copymay include specific information identifying it as a duplicate.Information from the electronic receipts is aggregated by the electronicreceipts administration system 24 for the purpose of reporting as forinstance in the case of customer service, or base device performancemanagement. Such aggregated information may also be provided by theelectronic receipts administration system 24 to other systems and/orservices for various purposes, such as, tax reporting. The electronicreceipts administration system 24 may further use the aggregatedinformation to respond to administrative queries from the base device14, such as, requests for electronic receipt back-up restoration orrequests for receipt proofing based on comparison with a duplicate.

The system 10 operates in the following exemplary manner. When the userof the portable device 12 wishes to conduct a transaction with theservice provider, the user directs the portable device 12 to interactwith the base device 14, for example, by inserting the portable device12 into the base device 14. The base device 14 retrieves informationfrom the portable device 12 and, optionally, receives information fromother peripheral devices, such as, an electronic cash register. The basedevice 14 then uses such information as well as other information thatis available locally to produce an electronic receipt for thetransaction. Information that is available locally includes, forexample, unique base device characteristics, such as, the UBDID, andpolicies and terms and conditions for generating electronic receipts forthe specific service provider. The electronic receipt is then providedto the portable device 12 where the electronic receipt is stored. Aduplicate copy of the electronic receipt may be retained and stored inthe base device 14.

Preferably, data contained in the electronic receipt is protectedagainst tampering, and optionally against retrieval by an unauthorizedsource. The electronic receipt contains a variety of informationincluding, for example, receipt status information (such as original,duplicated, invalid and deleted); a substantially unique receiptidentifier; substantially unique transaction identifying information,such as, a transaction ID generated by the service provider, date, time,transaction amount when payment occurred, information on products andservices delivered, and validity period; base device information, suchas, the UBDID; a variable number of line items, each with a variablenumber of transaction specific information, such as, line item productor service obtained, price, terms and conditions of service; uniqueportable device identification information linking the electronicreceipt to the portable device; account information linking theelectronic receipt to the payment account used to pay for thetransaction; and portable device user information.

The electronic receipt can also be displayed by the base device 14 andthe user device 16. Depending on the respective configurations of thebase device 14 and the user device 16, the electronic receipt can bedisplayed in different formats.

Electronic receipts may have individually or collectively defined accessconditions identifying methods and/or security mechanisms that need tobe satisfied in order to perform functions associated with theelectronic receipts, such as, viewing, uploading, and canceling.

Electronic receipts are stored as logical records within data structuresin the portable device 12 and optionally the base and user devices 14and 16. In one embodiment, a record or data structure for storing anelectronic receipt may contain a header, content descriptors and data.The header contains such information as may be required to (1) uniquelyretrieve the electronic receipt stored in the portable device (such asstart address, length for instance); (2) identify the electronic receipt(such as substantially unique receipt identifier); (3) link theelectronic receipt to an UBDID; (4) implement receipt access conditions,and receipt confidentiality protection; and (5) identify the receiptstate (including but not limited to the following three states: valid,canceled, copy).

The content descriptor includes information required to identify andretrieve any single field of an electronic receipt stored on theportable device 12, the base device 14 and the user device 16. Suchdescriptor may contain data labels or tags, and data lengths, usingproprietary or standard specification as defined by the administrationservice provider environment 20.

In one embodiment, a record used for storing an electronic receiptincludes a number of special fields. The special fields include avariety of data including, for example, (1) data used in the process ofvalidating the integrity of the electronic receipt (tamper detection),such as, the result of a checksum or one-way hash function; (2) date ofreceipt creation and receipt validity period; (3) data identifying theportable device 14 on which the electronic receipt is first stored; (4)data which allow receipt management functions, such as, receipttransfer, receipt back-up, receipt duplication, and automatic receiptdeletion at the end of its validity period.

The record used for storing an electronic receipt further includes anumber of data fields which include (1) date and time of transaction;(2) reference or description of products and/or services provided; (3)price, payment terms and payment status; (4) portable device userinformation, such as, name or address; (5) base device defined datarelated to receipt formatting and presentation, such as, definitions ofsize, fonts, color, orientation, logos, brands or trademarks, or keymessages specific to the user.

The storage of electronic receipts on the portable device 12 islogically structured so as to allow a number of functionality. Forexample, the base device 14 is able to scan through electronic receiptsto identify which ones are related to or can be managed by the basedevice 14, without bypassing receipt access control conditions. The basedevice 14 is able to delete any expired electronic receipt (beyond itsvalidity period) for which automatic deletion is allowed. The basedevice 14 is also able to verify the integrity of an electronic receipt.The portable device 12 is able to respond to a query for retrieving anelectronic receipt from the base device 14 by satisfying the necessaryaccess condition requirements, if any, defined in relation with theelectronic receipt. In addition, the portable device 12 is able torespond to retrieval request from the user device 16, providing multipleelectronic receipts upon satisfaction of a general retrieval accesscondition. The portable device 12 is able to refuse storage of anelectronic receipt under certain conditions including, for example, whenthe memory capacity of the portable device 12 is exceeded.

In one embodiment, a number of data and file structures can beimplemented to allow for the foregoing functionality, including, forexample, (i) a receipt directory containing the receipt headers and thenecessary pointers to the actual electronic receipt in a receiptdatabase; (ii) the receipt database indexed by UBDID and receipt ID; and(iii) a flat file of predefined length, including for each electronicreceipt a header followed by sequences of descriptor/data pairs.

Electronic receipts that may be off-loaded from the portable device 12are linked with the portable device 12 for tracking purposes. Theportable device 12 includes a unique identifier defined by the issuer ofthe portable device 12. The portable device identifier may be a fixed orvariable length identifier. Electronic receipts generated by theportable device 12 include such unique identifier and, optionally, userinformation, such as, name, address and information relating to paymentaccounts that may be linked to the portable device 12 and used in thecontext of a transaction. User information may be constructed as fixedor variable length records with predefined contents or a set of variablelength records made up of descriptor and data fields, the descriptorfields identifying the nature and length of the data, the data fieldsincluding such data as required to identify the user.

Electronic receipts can be manipulated in a wide variety of ways, aswill be further described below. Generally, an electronic receipt iscreated and delivered at a point of service. Creation of an electronicreceipt is initiated when the portable device 12 interacts with the basedevice 14. The base device 14 prompts for the portable device 12 used inthe transaction and validates its ability to receive and storeelectronic receipts. The base device 14 then generates the receipt dataand receipt records, based on the receipt policy associated with thetransaction. In one implementation, the base device 14 contains theappropriate receipt policy; in an alternative implementation, the basedevice 14 obtains the appropriate receipt policy by queryingcomplementary systems associated with the transaction, for instance, acash register or the electronic receipts administration system 24. Thebase device 14 then communicates the electronic receipt to the portabledevice 12 for storage. The base device 14 may locally maintain aduplicate copy of the electronic receipt and an activity log of thereceipt generation. The duplicate electronic receipt and data from theactivity log can be uploaded to the electronic receipts administrativesystem at a later time.

An electronic receipt can be retrieved at the point of delivery of aservice. In order to conduct a transaction, the base device 14 mayrequire the retrieval of an electronic receipt previously stored on theportable device 12, for instance, in the case of a claim ticket. Thebase device 14 queries the portable device 12 and scans the electronicreceipts stored on the portable device 12 to identify the appropriateelectronic receipt using identification information, such as, an UBDIDand relevant transaction information. The use of the UBDID allows thebase device 14 to identify electronic receipts that it generated. Thebase device 14 and the portable device 12 then identify and execute theoperations, if any, associated with the access control conditions forthe electronic receipt, including but not limited to, verification of auser PIN or other means which indicates the positive acceptance by theuser of access to the electronic receipt. Upon retrieval of theelectronic receipt, the base device 14 checks, if required, the validityof the electronic receipt. In the case of multiple electronic receiptshaving been retrieved, the base device 14 may prompt the user to selectthe appropriate one based on such information contained in theelectronic receipts as a receipt ID, a transaction date, a transactionamount or a product or service descriptor. The base device 14 maylocally maintain a log of the electronic receipts retrieved for laterupload to the electronic receipt administration system 20.

An electronic receipt can be deleted or canceled on the portable device12. The base device 14 having retrieved an electronic receipt from theportable device 12 may require its deletion in the portable device 12 toavoid exception situation at a later date, such as, fraudulent claims.This would be the case, for instance, in the case of a claim ticketexchanged for a high value item. For example, upon a user requestingredemption for a service or merchandise, the base device 14 retrieves acorresponding electronic receipt from the portable device 12. Once theservice or merchandise is redeemed, the corresponding electronic receipton the portable device 12 is deleted from the portable device 12. Areceipt deletion is requested by the base device 14 but executed by theportable device 12, in accordance with access control conditions. Anelectronic receipt can be logically deleted (or cancelled) by alteringits state indicator, thus allowing the user to later upload theinformation to the user device 16; or the electronic receipt can bephysically deleted from the memory of the portable device 12 to free upstorage space. The base device 14 may locally maintain a log of thereceipt deletion or cancellation for later upload to the electronicreceipts administrative system 24.

Expired electronic receipts can also be deleted or canceled on theportable device 12. According to the receipt management policy andaccess control conditions, if any, defined for an electronic receipt,the base device 14 may optionally cancel electronic receipts stored inthe portable device 12 that are no longer valid. This function ensuresthat portable device memory is optimally used. Execution of suchfunction may occur during any of the interactions between the basedevice 14 and the portable device 12, and, preferably, in instanceswhere a new electronic receipt is created and stored on the portabledevice 12. The base device 14 may locally log information about thecanceled electronic receipts for later upload to the electronic receiptsadministrative system 24.

Electronic receipts stored on the portable device 12 can be displayedfor management by the user. The portable device 12 may be queried by theuser using the user device 16 looking to retrieve information on some orall the electronic receipts stored on the portable device 12 in order tofacilitate receipt management. Examples of use of this function would beto allow receipt display and sorting by the user as a preamble to othermanagement activities. Electronic receipts that are to be retrieved anddisplayed may be subject to management and access conditions,individually or collectively. For example, the user device 16 may needto satisfy a general access condition applicable to a specific group ofelectronic receipts. Depending on the management and access conditions,receipt information may not be copied and retained on the user device 16for a number of reasons including, for example, preventing fraudulentduplication and use.

A user using the user device 16 to review electronic receipts on theportable device 12 may find it desirable to manage such receipts in anumber of ways including, for example, receipt duplication, storage,sharing, deletion or cancellation, and restoration.

An electronic receipt is duplicated when a copy is uploaded from theportable device 12 into the user device 16 or the base device 14. Thestatus information contained in the copy may be updated so as to reflectthe duplication so as to, for example, avoid fraudulent use ofreproduced receipts.

An electronic receipt is stored or parked when it is uploaded from theportable device 12 into the user device 16 and the original copy in theportable device 12 is deleted. Parking an electronic receipt isperformed to free memory from the portable device 12 without permanentlylosing the electronic receipt. Parking the electronic receipt allows forits later use by downloading it back to the portable device 12. Parkingof an electronic receipt may be subject to the fulfillment of managementand access control conditions, if any.

An electronic receipt is exported when the transaction information itcontains is made available to a different application in or via the basedevice 14 or the user device 16. For example, information from anelectronic receipt may be provided to an accounting application. Theaccounting application may reside in or be external to the base device14 or the user device 16. Exporting an electronic receipt is not akin toduplicating it in that not all the information in the electronic receiptis reproduced. For example, administrative information associated withthe electronic receipt, such as, the management and access controlconditions, may not be duplicated. Exporting of an electronic receiptmay be subject to the fulfillment of management and access controlconditions.

Deleting or canceling an electronic receipt renders it invalid. Adeletion is a physical removal of the electronic receipt from storage. Acancellation is a logical equivalent of a deletion by altering a statecode. A canceled electronic receipt may be overwritten at any time by anew electronic receipt. Depending on the management and access controlconditions, receipt deletion/cancellation can occur by choice of theuser or automatically (e.g., for expired receipts) at the base device14.

Receipt restoration may occur in the case of the loss of the originalelectronic receipt. This may happen in the case of the replacement of alost or defective portable device 12 or as part of the periodicre-issuance of the portable device 12. Receipt restoration is a functionof the electronic receipt management policy defined by the electronicreceipts administration system 24. Receipt restoration involvesretrieving a duplicate or backup copy of the original electronicreceipt, downloading the duplicate or backup copy to the portable device12 and updating the duplicate or backup copy to be recognized as themaster or original copy of the electronic receipt. Receipt restorationmay occur at the user device 16 or the base device 14 and may requirethe devices 14 and 16 to connect to the electronic receipt managementserver 18 and/or the electronic receipts administration system 24 toobtain approval of the action. In addition, the electronic receiptmanagement server 18 and the electronic receipts administration system24 may cooperate with each other, such as exchanging requisiteinformation, to provide receipt restoration. Restoration of anelectronic receipt may be subject to the fulfillment of one or moremanagement and/or access conditions, if any.

The electronic receipts administration system 24 is capable ofperforming a number of operations. For example, electronic receipts maybe retrieved for information management by the service provider via theelectronic receipts administration system 24. Information contained inthe electronic receipts may be of value to the service provider not onlyat the point of sales but also in the context of certain back officeoperations. The service provider may via the electronic receiptsadministration system 24 upload copies of the electronic receipts storedin the base device 14 under its supervision and export the transactioninformation contained in these receipts for use by other systems orproviders. For instance, information contained in an electronic receiptpertaining to a purchase may be used to resolve disputes about thetransaction. Receipt exporting may also allow the service provider toextract performance statistics or usage information about the systems,including that which may be used to assess participation and billing toservice providers or fraud detection and management.

In addition, the electronic receipts administration system 24 may alsocollect information from the base device 14 to facilitate base devicesmanagement. For example, statistics relating to transactions processedby the base device 14 may be used by the electronic administrationsystem 24 to analyze performance of the base device 14 and allow thebase device 14 to be managed more efficiently.

Receipt restoration can be an important component of customer service.Electronic receipt restoration can generate additional consumer benefitsover paper receipts which can be easily lost or damaged.
